MMF Qestions

Hi all ! I am very new here but I have to say I have learne a tremedous amount of info. The photos on this site are wonderful. I do have a few questions about MMF. I made my first batch yesterday. I have never used fondant of any time only buttercream and a couple of times royal icing (hate it ) My question is if I shape my MMF to the shape I want, I realize it has to dry, but how long is it good for. I have a cake due in 2 weeks, and was playing last night making a camoflauge hat. It turned out realy good and was hoping it will last til I do the cake. But not sure how long fondant last. Could someoneplease help me out on this one. Thanks so much.

I think it really depends on your climate. For me, it takes way longer in the hot, humid months than it does in the dead of winter when it's so dry. I'm making MMF flowers for the top of my daughter's 11th birthday cake (it's Thursday!) and I'm keeping my fingers crossed that they set up in time. We're suppose to have nice, dry weather all week, so chances are everything will be fine.
